[texts]FIR Filter Implementation by Systolization using DA-based Decomposition
In this paper we present 1D and 2D systolic Distributed Arithmetic (DA) based structures that are designed for the implementation of Finite Impulse Response (FIR) filters. The paper compares the 1D DA based systolic structure with 1D systolic DA based decomposition method. The filters are implemented on a Xilinx Virtex II Pro (XC2VP30) FPGA using HDL and system metrics like Area, Gate Count, MaximumUsable Frequency and Power consumption are estimated for different filter orders and address lengt...

[texts]FIR Filter Design using Particle Swarm Optimization with Constriction Factor and Inertia Weight Approach
This paper presents an alternative approach for the design of linear phase digital low pass FIR filter using Particle Swarm Optimization with Constriction Factor and Inertia Weight Approach (PSO-CFIWA). FIR filter design is a multimodal optimization problem. The conventional gradient based optimization techniques are not efficient for digital filter design. Given the filter specification to be realized, PSO algorithm generates a set of filter coefficients and tries to meet the ideal frequency ch...

[texts]Design And Performance of Finite impulse Response Filter Using Hyperbolic Cosine Window - Harish Kumar, Piyush Kumar and Kaushal Kumar,Venkat babu G
In this paper a proposed of design and analysis of Finite impulse response filter using Hyperbolic Cosine window (Cosh window for short). This window is very useful for some applications such as beam forming, filter design, and speech processing. Digital FIR filter designed by Kaiser window has a better far-end stop-band attenuation than filter designed by the other previously well known adjustable windows such as Dolph-Chebyshev and Saramaki, which are special cases of Ultraspherical windows, b...
